It's not even that climate measures are costly, they're a net positive in the long run! But nobody is interested in the long run, because the filthy rich live in an alternate universe where they will live forever in luxury far away from the filth of the rest of us.
The sci-fi book Children of Ruin (sequel to Children of Time) covers this somewhat. There humans encounter a planet with a breathable atmosphere but with a toxic environment that slowly kills them.
An immortal character from Doctor Who also covered this. She chronicles her life in a library of diaries but also destroyed some of them when the memories were too painful (her own children dying of old age).

Honestly, almost all their shows make me at least curious to watch an episode. Several got me hooked (Severance, Foundation, Silo, Shrinking, Murderbot).
According to research led by Dr Paul McDonald, Senior lecturer at the University of Wolverhampton’s School of Humanities, Languages and Social Sciences, the oldest example of recorded humour dates back to at least 1900 BC and is a Sumerian proverb warning new husbands about their flatulent brides: "Something which has never occurred since time immemorial; a young woman did not fart in her husband’s lap." The joke, which follows a structure, was found on tablets from the Old Babylonian period but may date back as far as 2,300 BC.

Und CEOs die sich der Entwicklung verwehren, werden nach Pleitegang eh nur mit dem nächsten CEO-Posten und einem goldenen Fallschirm belohnt. Also warum etwas ändern?
Fascism is inherently self-destructive, so that won't happen. But the collapse will cost a lot of human lives.
